About formats

JBG is a file extension for images compressed using the JBIG (Joint Bi-level Image experts Group) standard, formally ITU-T Recommendation T.82, completed in 1993 as a successor to the Group 3 and Group 4 fax compression standards. JBIG compression is designed for bi-level (black and white) images but can also handle grayscale and limited-color images by encoding each bit plane separately. The algorithm uses a form of arithmetic coding guided by an adaptive context model: for each pixel, the encoder examines a template of surrounding already-coded pixels to build a probability estimate, then feeds this estimate to a QM-coder (a variant of the Q-coder arithmetic coder) that produces a highly efficient binary output. JBIG achieves 20-40% better compression than Group 4 on typical document images, with the improvement being even larger on halftoned photographs and images with gradual density transitions where Group 4's simple run-length approach is less effective. The standard supports progressive encoding, where a low-resolution version of the image is transmitted first and progressively refined — useful for fax-like applications where the receiver can begin displaying the image before the full-resolution data arrives. One advantage is superior compression of documents containing halftone images: newspapers, magazines, and marketing materials that mix text with photographic halftones compress dramatically better with JBIG than with Group 3/4. The standard's ITU-T backing ensures it is implemented in document imaging hardware and software worldwide. JBG files are supported by ImageMagick and various document imaging tools.

DOT is the binary template format for Microsoft Word, using the same OLE2 compound document structure as DOC files. A DOT file contains a complete document framework — styles, page layout, margins, headers and footers, boilerplate text, macros, AutoText entries, toolbar customizations, and keyboard shortcuts — that serves as a reusable foundation for creating new documents with consistent formatting. When a user creates a new document based on a DOT template, Word generates a fresh untitled DOC pre-populated with the template's content and styling while leaving the original template file unmodified. The format supports every feature available in DOC, including complex formatting, embedded objects, form fields, and VBA macro code. The Normal.dot file holds particular significance as Word's global template, storing default styles, macros, and customizations that apply to all new blank documents. DOT templates became essential to enterprise document management, ensuring that legal contracts, business letters, technical reports, and corporate communications consistently adhered to organizational formatting standards. One advantage is brand and compliance consistency — distributing DOT files across an organization guarantees uniform document appearance without relying on individual users to manually configure styles and layouts. While the XML-based DOTX format has replaced DOT for modern workflows, the binary template format remains in use in environments requiring Word 97-2003 compatibility and in legacy template libraries.
